PC-USB Pressure Tuner Controller

The Lunt PC-USB is a microprocessor controlled, remote operable pressure control system that can be retrofitted to any Lunt pressure-tuner product, enabling observers to eliminate telescope vibration during tuning. The controller achieves 0.3 PSI precision while automatically compensating for internal pressure fluctuations caused by temperature changes, and provides closed-loop feedback of internal etalon pressure so users can correlate changes in pressure to Doppler-shifted events. The PC-USB can be operated manually via the control panel or remotely via computer using USB connection (Windows 7 or higher required), making it ideal for both remote observatories and field observations.
